Specification of Letters Patent..

Patented Mar. 5, 1918.

Application led December 26, 1916. Serial No. 138,786.

To al?) whom it may concern:

Be it known that I, Gnonon R. S'riivn, a citizen of the United States, residing at Ualrland, in the county of Alameda and State of California, have invented new and useful Improvements in Folding Camp- Stools, of which the following is a specification.`

This invention relates to a folding camp stool.

@ne of the objects of the present invention is to provide a simple, compact, rigid folding camp-stool comprising a tubular metal container, a plurality of legs, and arms supporting a fabric seat section, and particularly to provide a structure which permits folding and telescoping of the seat, legs and arms within the container, as will hereinafter be more fully described. Further objects will hereinafter appear.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1 is a side elevation of a container, showing the seat section and supporting arms telescoped within the container and the supporting legs folded and secured by the upper cap.

Fig. 2 is a central, vertical, longitudinal section of Fig. 1.

Fig. 3 is a similar section, showing the seat and supporting legs extended.

Fig. et is a cross section on line .ir-#l of Fig. 3.

Fig. 5 is a cross section on line 5-5 of Fig. 3.

Fig. 6 is an enlarged, sectional, detail view of the lower end of the container, showing the pivotal mounting and supporting legs.

Fig. 7 is an enlarged, detail plan view, showing the connection formed between the fabric seat and one of the supporting arms.

Referring to the drawings in detail, A :indicates a standard or tubular container which, in this instance, is octagonal in cross section and provided with four channels, such as indicated at 2, in its exterior surface which extend from end to end of the container. The lower end of the container is provided with a flaring bottom section 3 which is adapted to receive a screw l and a clamping disk 5.

Fivotally mounted, as at 6, in the lower end of each channel 2 is a supporting leg 7 which is adapted to be swung about the pivots or hinges G to lie within the channels 2 or swung about the pivots to assume the extended position shown in Figs. 3 and 6 where they are adapted to be rigidly secured by means of the clamping plate and the screw t. The plate is slotted to receive the legs 7 and the slots are cut on an angle, such as shown in Fig. G, to form a rigid support and lock which prevents the legs from spreading, when extended. The clamping plate is removed by unscrewing the screw d when the legs are further folded in their receiving channels 2. It may then be replaced and will then serve as a lock to prevent unfolding of the legs.

Slidably mounted, interiorly of the container, is a piston member 8 which is peripherally slotted to receive four arms, such as indicated at 9; each arm being pivotally mounted, as at 10, in the slotted section of the piston to permit each arm to be extended or folded, as will hereinafter be described. The arms are provided as a support for a canvas seat 11, which is secured between the upper ends of the arms by a clip 12, such as shown in Figs. 3 and 7. The canvas or fabric seat employed and the supporting arms 9 are adapted to be folded and tele scoped within the container and are also adapted to be loclred against movement, when extended, by means of a cap 13. The lower end of this cap is slotted, as at le, to straddle the arms and it is also provided with a screw 15 which is adapted to be received by the piston 8. The upward movement of lthe piston within the container is limited by a plurality of inwardly turned stopping lugs 16 and it is, therefore, possible, when the screw 15 is tightened, to draw the cap down against the arms to such.

an extent that the fabric seat will be stretched and the arms rigidly secured against pivotal movement.

lf it is desired to re-fold the seat and place it within the container, it is only neces sary to remove the cap 13. The arms 9 may then be swung to a vertical position and the seat section 11 folded between saine. The arms and seat, together with the piston 8, are then forced down into the container until the position shown in Fig. 2 is assumed.

The cap 13 may then be replaced and will thus exclude rain or dust. The cap, furthermore, is suiiiciently long to close the upper ends of the supporting legs `when these are folded into their receiving channels, and therefore positively secure the same against swinging out or away from the container during shipment.

A folding and collapsible stool constructed as here shown takes up a comparatively small space, when folded, and also forms a convenient package which may be :stored away or easily `transported when camping or traveling. The supporting legs and arms employed are preferably made of channel iron while the container proper is made of pressed sheet steel. This material provides a rigid structure which can stand any amount of use, wear and tear or rough handling without falling to pieces or becoming easily' destroyed. Any slack or stretch produced in the seat section may be talren up at any time by the screw l5 and the cover section 13 and any play or wear produced in the hinges 6 may also be taken up by the clamping plate 5 and the screw 4. The chair, when folded and collapsed within the container, makes a compact bundle and when extended provides a full-sized stool for ordinary use.` y y Having thus described my invention, what I claim and desire to secure by Letters Patent isy 1. A folding camp stool comprising a tubular container, a piston slidably mounted therein, a plurality of arms pivot-ally connected to said piston at their lower ends, a fabric seat section secured between the upper ends of the arms, said arms adapted to assume a vertical position and the seat a folded condition between the arms to permit telescoping of the arms and seat within the container, means permitting the arms and seat to be extended when the piston is moved to the upper end of the container, means for locking the piston and arms against moven ment when in said position, said means comprising a slotted cover adapted to fit the upper end of the tube and straddle the arms, a plurality of stop lugs with which the pis* ton is engageable, and a screw adapted to clamp the cover and piston together.

2. VA folding camp stool comprising atubular container having a plurality of channels formed in its exterior surface, a plurality of sulmorting` legs pivotally mounted, one in each channel, adapted to be` folded into the channels or extended to support the container, a telesc'oping` seat member carried by the container, and means for loclringv the legs either in the folded or unfolded position.,

3. A folding camp stool comprising a tubular container having a plurality of channels formed in its exterior surface a plurality of supporting legs pivot/ally mounted, one in cac-h channel, adapted to be folded into the channels or extended to support the container, a telescoping seat member carried by the-container, means for locking the legs either in the folded or unfolded position, said means comprising a clamping plate adapted to engage the legs, and a screw extending through said plate `and the bottom of the container.
